1'0 aZZ whom it may concern:

Be it known that 1, CHARLES W. LEWIs, a citizen of the United States,residing in the borough of Manhattan, in the city, county,

5 and State of New York, have invented certain new and usefulImprovements in Knockdown Paper Boxes, of which the following is aspecification.

This invention relates to the general class of boxes or crates made frompaper fabric in several separate parts, each of which is adapted to bepresssd out flat for packing or shipment, but when folded and telescopedone within the other they form a box or receptacle.

The object of the present invention is to provide a very strong andstiff box or receptacle made up from three separate and distincttelescoping parts.

In the accompanying drawings, Figure 1 is a perspective view of the boxwith all the parts telescoped and the cover partly open. Fig. 2represents in perspective the outer casing or part detached. Fig. 3represents in perspective the intermediate section or part detached.Fig. 4 is a perspective View of the inner section or part detached.Figs. 5 and 6 are sectional views of the box on asomewhat larger scale,the former being a vertical section in the plane indicated by line .00in Fig.

2 and the latter a vertical section in the plane indicated by line 00 inFig. 2.

The material from which the box is made is what is known as cellularboard, which is composed of two fiat sheets of paper andan in- 5termediate corrugated sheet pasted between them.

A designates the outer casing or part of the box. This casing, which isin the form of a rectangular tube open at the ends, is preferably formedof a single sheet of the fabric, with the corrugations extendingroundwise and the hingingcreases extending transversely of thecorrugations. The meeting ends of the sheet of fabric are connected to-5 gether by a hinging-strip a, of some suitable fabric. The intermediatesection or part B (seen detached in Fig. 3) has the corrugationsextending lengthwise of the strip or piece. It consists of three fullsides I) and two halfsides or flaps b at the respective ends of thepiece. On one of these end flaps or half-sides is a tab W. This part Bwhen folded fits snugly into the casing A, so that the corrugations ofthe latter cross those of the former at right angles. The inner sectionor part 0 is shaped similarly to the section B and consists of threefull sides 0 and two half-sides or flaps c. In this part 0 thecorrugations extend lengthwise of the strip or piece, and when insertedin the intermediate section B the corrugations of the latter cross thoseof the former at right angles. The box thus composed of the telescopedparts A, B, and

0 forms a complete two-ply box of the cellular paper fabric wherein theintermediate section 6 B has its corrugations at right angles to thoseof the other two sections.

As seen in Fig. l, the box has an inner cover formed of the two flaps cand an outer cover formed of one of the full sides b of the section B,theflap or half-side b on this side forming the securing-tuck, which maybe drawn out by the tab 17 It will be noted that by telescoping thefolded strips B and C, so as to cross each other, the two plies of thebox-wall are made to extend to all the six sides of the box. The hingesof the several folding parts A, B, and O are formed by crushing thefabric along the hinging-lines.

The box will be rectangular, but may be of any desired size orproportions. The flap b, which bears the tab b may of course be wide ornarrow, as desired. In Fig. 5 it is represented as narrower than theother flap b.

Preferably the inner covering-flaps c on the section 0 will be of equalwidth, as shown; but obviously this is not essential to the invention.This flap might be full, like the cover-flaps b b of the section B.

Having thus described my invention, I claim- 1. A knockdown box madefrom stiff, cellular paper fabric, in three separable or distinct partsfolded and telescoped together, each of the six sides of said boxconsisting of two non-adherent plies or thicknesses of said cellularfabric, and said plies having their corrugations crossing at rightangles.

2. A box made from stiff paper in three I00 separable, distinct parts,the outer part being in the form of a rectangular open-ended tube, theintermediate part composed of sides or sections hinged together, theends of said part being free or disconnected and the inner part,telescoped within and crossing the intermediate part, said inner partbeing composed of sides or sections hinged together and having its endsfree or disconnected, said intermediate and inner parts having cover andtucking flaps.

3. A square, knockdown box made from stifli, cellular paper fabric inthree separable parts or pieces, namely, the tubular outer casing A, thefolded intermediate part B, having a tuck or tucking-flap at one end,and the foldedinner part C, telescoped within and crossing the part B,said part '0 having two inner cover-flaps 0, substantiallyas set forth.

4. A knockdown box made from stiff paper in three separable or distinctparts, the outer part being in the form of a rectangular tube, hinged atits corners so that it may be flattened for packing, the intermediatepart, composed of sides or sections hinged together so that the part maybe flattened for packing, and the inner part, telescoped Within andcrossing the intermediate part, said inner part being composed of sidesor sections hinged together so that the part may be flattened forpacking, said intermediate and inner part having a cover and tuckingflaps, substantially as set forth. In witness whereof I have hereuntosigned my name, this 7th day of January, 1901, in the presence of twosubscribing Witnesses. CHARLES W. LEWIS.
